I'll post a reply if I find anything.<br /><br />thanksAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6511639843549834846.post-30013309680747618022013-01-05T17:32:58.965-08:002013-01-05T17:32:58.965-08:00I was able to rotate the framebuffer using:

Perhaps I'm not doing it correctly.<br /><br />I will try it again on monday. I had tried so many things the other day, perhaps I'm mistaken. I'd like to verify. <br />Thanks again for your help.<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6511639843549834846.post-36076431191617688322013-01-05T10:48:56.615-08:002013-01-05T10:48:56.615-08:00Hello, glad that you were able to get it to work. ...Hello, glad that you were able to get it to work. Since this is eglfs, wouldnt you be able to change the framebuffer setting and restart the graphics drivers, to get the effective rotation ?Anonymoushttps://www.blogger.com/profile/05152030313769592813noreply@blogger.comtag:blogger.com,1999:blog-6511639843549834846.post-51099985897908284152013-01-04T10:44:15.570-08:002013-01-04T10:44:15.570-08:00Prabindh,
This blog has been extremely helpful. I...Prabindh,<br />This blog has been extremely helpful. It's helped me get Qt 5.0/eglfs/OpenGles2 running on a ti am335x devkit. kernel 3.2.34 and Graphics_SDK_4_08_00_01. <br /><br />Ogles2 demos and Qt5 applications are working. Starting the Qt5 app with -platform eglfs. <br /><br />Only place I'm stuck is we need the application to run in portrait orientation instead of landscape. Qt4x with qws was as simple as -display transformed:Rot270. <br /><br />Your blog has screen rotation as todo :) I was hoping you may have some pointers, maybe something simple I'm missing. Before I start digging into the Qpa/kernel/driver sources.<br /><br />thanks for you work<br />Anonymousnoreply@blogger.com
